It's a National Sport all over the region and they are masters at what we call haggling. If you'd like an indicator of how not to do it, see our President's Now Ruz message to Iran.

They will only negotiate from a position of strength. If they do not believe their strength is adequate to get what they want, they will delay, whine, bluster and obfuscate until such time as they believe they're strong enough to prevail. They view ANY compromise as weakness.

Yes, they negotiate -- and we're rank amateurs at it and should be very cautious about entering into negotiations with them. In fact, some of the factors of our behavior in the ME about which you complain frequently were induced from earlier negotiations with various regimes in the ME wherein we foolishly bought a bill of goods because we thought they negotiated in good faith and meant what they said. Or would stick to an agreement after it no longer suited...

That said, I agree with your first point.
